The 3rd RockHoundLounge Personal Collections series is here with Dennis Herman.
Dennis W. Herman - Biography
Dennis, a retired herpetologist/naturalist/biologist and a native of Burke County, developed a deep appreciation and love of nature, especially animals, at the age of 4. Inspired and encouraged by his 4th Grade teacher to collect rocks and minerals, Dennis became a rockhound in 1958, often searching plowed fields near his house (and during visits to friends and relatives) for crystals and Native American artifacts. It wasn’t until after his family moved to Mitchell Co. in 1961 that he was able to pursue his love of nature, with non-school time spent searching for and collecting rocks, minerals, and small critters, especially amphibians and reptiles.
Mineral collecting opportunities were readily available while living a few miles west of Spruce Pine from 1961-1971. Several mica and feldspar mines were very close to the house, and many hours were spent checking the mine dumps for specimens. These mines contained almandine garnets (single xls, clusters, and included in muscovite), feldspar xls, muscovite xls, and various rare earth and uranium minerals (columbite, samarskite, uraninite, clarkeite, zircon var. cryolite, autunite, torbernite, and uranophane). One prospect yielded yellow to greenish yellow beryl xls, my favorite mineral species. Other Mitchell Co. mines, i.e. Crabtree Emerald Mine, Chalk Mountain Mine, Hoppus Mine, Biggerstaff Branch Mine, and Chestnut Flat Mine provide specimens for my collection. Mineral collecting waned during much of my high school and college years to concentrate on my studies and other budding interests.
After receiving a BS in Biology from Western Carolina University, Dennis moved to Atlanta, GA in 1972 where he worked at the Atlanta Zoo for 24 years as a keeper and Assistant Curator of Herpetology. Mineral collecting took a back seat during his zoo employment, but he did continue to collect specimens during zoo trips for reptiles and amphibians. Fossils became his focus during the zoo years; with forays to Edisto Island Beach (South Carolina), the Durham coal mines and trilobite sites in northwest Georgia, and the Cretaceous areas of west Texas.
Dennis began working for the state of North Carolina in 1996 as the Coordinator of Living Collections for the N.C. Museum of Natural Sciences where he assisted in leading museum's public field trips for rocks and minerals to various localities, such as Hamme Tungsten Mine, Mitchell Co. mines, and Glendon pyrophyllite mine, and others. In 2004 he left the museum to work for the North Carolina Department of Transportation (NCDOT) as an environmental program consultant with the Biological Survey Group.
In early 2006, Dennis realized the need to design a database for his collection. The database includes detailed mineral and locality data, as well as photographs. Each specimen is assigned a number, and attached to the specimen. Specimen cards were designed to include the specimen #, mineral species, locality, and provenance, if known. A photograph of the specimen is located on the reverse side of the card. Due to physical problems, Dennis no longer actively searches for or digs for specimens, but an occasional walk through a plowed field or old mine dump is still enjoyable. Much of the collection contains specimens purchased or traded for now, with only about 25% personally collected.
Dennis retired from state government in June 2014, and lives with his wife, Amy, in Morganton. His time is spent eating good BBQ, maintaining his collection of N.C. gems and minerals, hiking in the N.C. mountains, searching mountain fens for bog turtles and rare plants, and working crossword puzzles.

At Gold Rush Expeditions we receive quite a few inquiries about what gold ore looks like on a daily basis. In response we've put together this video from our own personal ore collection. These nine samples convey a wide gamut of ore types from the desert locales of the far southwest to the high elevations of Colorado and Montana. We hope that this will help you the prospective Miner in all of your mining adventures. Good Luck, and get to finding that gold!

So today I will tell you about the most rare metal on Earth - iridium.
Iridium is a transitional metal, which is located in the middle of the periodic table, below rhodium. If we take a look at the prevalence of all elements in the earth's crust, Iridium holds the last place, that is a billion atoms of all that there is and only one atom of iridium. This metal is 40 times rarer than gold.
In much higher concentrations iridium is found in meteorites and also in the depths of the Earth, in magma. Interestingly enough, in the layers of rock sediments, though more precisely in the formation of clay, that is aged about 66 million years there were found high concentrations of iridium and this can indicate the collision of Earth with a huge meteorite in the past, which in theory was the cause of the death of the dinosaurs. In it’s appearance iridium is a shiny metal that does not oxidize in air.
This metal has almost the highest density of all metals, just 0.12% lower than that of osmium - the most dense metal.
In this tiny tiny metal droplet, which is of the size of a match head, we have 1 gram of iridium. To help you understand how high is the density of iridium, I will show other metals with the same mass for comparison.
Lead, copper, gallium, zinc, magnesium, and the lightest metal - lithium.
The volumes of the first and last metal differ by about 30 times, although their mass is the same. Iridium is also a very hard metal that is firmer than the solid steel in 1.5 (one and a half) times. Iridium, in addition to its rarity is even the most stable metal that does not oxidize in air up to 2000 degrees, and is not soluble in either acid or aqua regia. Iridium can only react with the fluorine at temperatures of about 600 degrees.
Unfortunately, due to the low activity of iridium, I cannot conduct any chemical experiments or have quality reactions with it.
The only thing that I can do is make a fine powder of iridium and set it on fire in the air, but as you can see, in this case iridium dust is burning quite slowly and also requires dispersing it in the air. For the first time on youtube, you can observe a burning iridium. Also, due to the low activity of iridium, the metal does not tarnish in air, even when heated to above 1,000 degrees. The only thing that the drop of iridium got covered with is a partially evaporated ceramic layer, the one that the forceps are made from. Iridium compounds are can be either brown or yellow, such as the complex of Vasca, which is used as a catalyst in organic chemistry.
By the way, Iridium is the only element that can give away 9 electrons and form compounds with +9 (plus nine) oxidation state.
Iridium now finds many uses in science and technology.
In most cases, we will probably find iridium in spark plugs for vehicles, due to the high stability of iridium to oxidation under the influence of electric discharge.
Pure iridium is used for making crucibles for growing single crystals, foil for making non-amalgam cathodes, as well as as a part of the highly resistant to corrosion alloys.
The first standard of mass of one kilogram was created in 1889 using an alloy composition of 90% platinum and 10% iridium and is called the International Prototype Kilogram, it is still kept in the Paris Chamber of Weights and Measures.
Now you know more about one more of the elements, if you would like the scientific series of the elements to continue, please subscribe to my channel and also throw in some likes if you can! Thank you for watching.

Exploring a large abandoned mine with special guests on Vancouver island called the Blue Grouse!
The Blue Grouse mine is located on the south side of Cowichan Lake, 4.8 kilometres northwest of Honeymoon Bay. Mineralized outcrops on the property were first located between 1900 and 1910. The mine was abandoned in 1960, reportedly leaving some reserves. The workings were rehabilitated in 1979 by Corrie Copper Ltd. Copper mineralization of mineable grade was reported to be present at the 1100 level. The workings were backfilled sometime between 1987 and 1989. The Sunnyside workings (092C 108) are located 800 metres to the south.
The Cowichan Lake area is at the eastern end of the Cowichan uplift, one of a series of major geanticlines on Vancouver Island. The area is underlain by pyroclastic, sedimentary and volcanic rocks of the Paleozoic Sicker Group, the Mississippian to Permian Buttle Lake Group, the Upper Triassic Vancouver Group and the Lower Jurassic Bonanza Group which have been intruded by Triassic gabbros (informally named Mount Hall) and Early to Middle Jurassic Island Plutonic Suite rocks, and overlapped by Upper Cretaceous sediments of the Nanaimo Group.
The Vancouver Group comprises pillow and massive basalt, volcaniclastics, tuffs and breccias of the Karmutsen Formation; siltstone, argillite and micrite of the Quatsino Formation and limestone, tuff and argillite of the Parson Bay Formation.
The property is underlain by Karmutsen Formation volcanics and Parson Bay Formation sediments. Sediments of the Nanaimo Group and volcanics of the Bonanza Group occur near the property. These are cut by numerous Jurassic feldspar and feldspar-pyroxene porphyry dykes related to the Bonanza Group.
The orebodies occur in limestone and tuffaceous members which are folded in a series of overturned folds. The beds are displaced by a series of thrust faults which have a general east strike and dips of 10 to 20 degrees south. Garnet-epidote-actinolite skarns are developed in limy tuff, limy sediments and limestone, apparently interbedded with the upper portions of Karmutsen Formation basalts.
Mineralization was present in ten small tabular sulphide zones and consisted of chalcopyrite, pyrrhotite, pyrite and lesser magnetite and sphalerite.
The main orebody, hosted in volcanic rocks, was the G-H. The ore consisted of a skarn zone which formed a southwest plunging pipe-like body extending from the surface to the 335 metre level. The mineralization comprised chalcopyrite, pyrite and pyrrhotite irregularly occurring as stringers and small masses. The orebody was displaced to the northeast, the top block moved 305 metres to the north and 46 to 61 metres to the east in relation to the lower block.
The E ore body, 300 metres due south of the G-H, was a 3 to 4 metre wide tuffaceous horizon mineralized with pyrrhotite. The pyrrhotite almost completely replaced the bedded rock and was veined with small stringers and irregular masses of chalcopyrite and pyrite. Small grains of hematite were noted locally.
The mine was in production from 1917 to 1919 and from 1956 to 1960. From 249,298 tonnes of rock, 6,814,623 kilograms of copper, 2,508,644 grams of silver and 218 grams of gold were produced. Exploration in 1989 located several gossanous zones in the southwest portion of the property. A 1-metre chip sample (109075) of intermediate tuff with copper staining from the BGN-4 site assayed 0.7 per cent copper and 0.043 gram per tonne gold (Assessment Report 19387). Sampling results ranged from 0.0007 to 1.1824 per cent copper and 0.001 to 0.043 gram per tonne gold (Assessment Report 19387). In 2002, Ber-Can Environmental Resources Inc. completed a program geochemical sampling of the Blue Grouse tailings and tailings ponds for the purpose of developing a proprietary process for the clean up of mine tailings and mill tailings.

March 28/16 - This video shows how fast arsenopyrite reacts to 35% hydrogen peroxide. The oxidizing effect is SUPER fast once the solution gets hot by chemical reaction.
This video series is to show the preparing of a gold specimen to make it more valuable than the gold content, this will turn out to be a museum quality specimen rather than crushing it and melting the gold.
The chemicals and techniques used in the preparation of this specimen are DANGEROUS and can cause death. This video is for educational purposes and hopefully entertaining as well. PLEASE DO NOT attempt any of these techniques or procedures without proper safety equipment and training

Senior business people in Vancouver with a unique wry smile and a twist of light in their eye recount eye witness episodes of Murray Pezim.
2. PRESIDENT, A GEOLOGIST, AT THE HARD ASSETS CONVENTION IN DOWNTOWN SAN FRANCISCO NOV 2009.
He let me pick up the 14,827 OPT-AU SPECIMEN THE SIZE OF AN AMERICAN HARDBALL, BUT IT FELT MUCH HEAVIER IN MY HAND. (They would not let me take it 400 yards to hold it in the sunlight on the sidewalk, nor trade it for a goldfoil wrapped chocolate medallion, but the president did let me hold it for a long time, so much so that I can still remember that unique stain against my forearm front muscle fibre strands.)

THESE SPECIMENS ARE FROM THE HISTORIC CROESUS GOLD MINE IN TIMMINS ONTARIO CANADA.
APPARENTLY CONSTANTINE HAS A DEPARTMENT JUST FOR THE SALES OF SUCH SPECIMENS. THEIR DISCOVERY IS ALSO A FASCINATING STORY.
1. 13,135 OZ PER TON
2. 14,827 OZ PER TON
3. 14,382 OZ PER TON
4. 17,575 OZ PER TON
5. 16,969 OZ PER TON
(None of them weigh a ton, that is their ratio to host rock prorated up to a ton.)
AND I THOUGHT A 20th CENTURY CANADIAN 2,OOO OPT DIAMOND CORE SAMPLE WAS HIGH. A SENIOR INVESTOR SAID HE WOULD NOT BELIEVE IT EVEN IF HE SAW IT, EVEN THOUGH I SHOWED IT TO HIM IN PRINT IN THE HEMLO BOOK BY MATTHEW HART. "LOOK FOR GOLD WHERE GOLD WAS FOUND" CAUTIONED ME ABOUT REPORTING SUCH INFORMATION. WELL THERE ARE NOW 5 OTHER WITNESSES THAT SUCH GRADES ARE NOT RELEGATED TO ONLY HISTORIC LEGENDS FROM THE 1800S GOLD RUSHES.
PAGE 117, PARAGRAPH 3: "The gold in the core in the photograph on Frank Lang's wall, from one of his Quebec properties, grades 3677.8 ounces of gold per ton."
PARAGRAPH 5: "Considerable amounts of free gold appear in the diamond drill core from Hole No. 29 of D'Or Val Mines Ltd.'s Beacon Property. While it assayed at 3677.8 ounces of gold per ton, this spectacular sample is not considered representative of overall grade."
NEXT PAGE: "But you never know what's down there, do you? You never know until you drill. ... In quartz, the gold is in veins. You could miss that by a quarter of millimeter, you'd never find it. How many more are there, that's all I ask. How much gold, just as rich as that, is down there?" - Frank Lang, legendary mining promoter, Hughes-Lang Group, downtown Vancouver BC Canada.
Quotes from book: "Golden Giant: Hemlo and the Rush for Canada's Gold"
By Matthew Hart, 1945-
Published by Douglas & McIntyre, (c) 1985, 176 pages
ISBN 0888944675, 9780888944672
http://www.amazon.com/Golden-giant-Hemlo-rush-Canadas/dp/0888944675/ref=sr_11_1?ie=UTF8&qid=1231795050&sr=11-1
My book is signed by Schiralli with message and is a textbook.
The 14,827 OPT-Au sample did hand-weigh approx 3 times more, than if solid steel. 16,000 OPT is half gold ore if considering 32,000 ounces per ton (OPT). The president of Constantine Metal Resources Ltd, a geologist, did say specific gravity testing was done on the 16,969 OPT specimen - the results indicated it breached 17,000 OPT but held to a lower figure so as to allow for a small percentage variance by another heavy metal, so the reported gold grade was toned down to 16,969 of oz/ton. Apparently they will never mill those samples.

003 - Geology
In this video Paul Andersen explains how rock is formed and changed on the planet. The video begins with a brief description of rocks, minerals, and the rock cycle. Plate tectonics is used to describe structure near plate boundaries. Hot spots and natural hazards (like volcanos, earthquake, and tsunamis) are included.

11. Pink Star
The Pink Star is the largest diamond in the world to be declared color wise as Fancy Vivid Pink by the Gemological Institute of America. The Pink Star was owned by the Geneva-based Steinmetz Diamond Group, who presented the 59.60 carat diamond to the world via a showing in Monaco in 2003.
10. The Vittle-s-bac Graff Diamond
This particular diamond got a bit of a change after it was sold at auction, and people weren't happy about it. The Vittle-s-bac Graff Diamond was bought by the legendary Sir Graff himself, and got the diamond for a little under $25 million dollars.
9. The Sunrise Ruby
In regards to the most expensive, or valuable, ruby in the world, there is only one choice, and that's the Sunrise Ruby. Why? Well, because when it was sold at an auction, it was valued and sold at $30 million dollars. There are some in the world who even value it as the "rarest of all gemstones". Some even go so far as to label it a "unique treasure of nature."
8. The Graff Pink Diamond
Pink diamonds are one of the most valuable diamonds in the world today, and one of the most valued ones ever is the Graff Pink Diamond. The diamond was once owned by Harry Winston, who kept the diamond for over 60 years. The 24.78 carat diamond was very special in numerous ways.
7. Oppen-hi-mer Blue Diamond
While colored diamonds are rare and special, few are as rare as the Oppen-hi-mer Blue Diamond. Why? Well, it's a pure blue that is just not found in nature very often, so to find this on a diamond of any size makes it special. Now, as for its owner, it used to be owned by one Sir Philip Oppenheimer, hence how the stone got its name.
6. De Beers Cent-en-ary Diamond
The De Beers Cent-en-ary Diamond breaks the bank in many ways when it was appraised at $100 million dollars. Making it one of the most valuable diamonds in the history of the world. But its history is also important.
5. The Star of Adam
When it comes to sapphires, there are simple versions, and then there are rare versions. One of the rarest of the gemstone is the Blue Star Sapphire, and in 2016, a man in Sri Lanka found the biggest one in the world. How big was it? Well, it was 1,404 carats. And though the owner remains anonymous, he values the massive blue sapphire at a whopping $300 million dollars.
4. Hope Diamond
The legendary Hope Diamond is legendary for numerous reasons. First and foremost, it's an incredibly valuable blue diamond, one measured to be 45.52 carats. In total, it's worth is approximately 350 million dollars. But while it is valuable, the "curse" of the object is arguably what people associate it more with.
3. The Cull-ee-nun
The Cull-ee-nun has the honor of being the biggest rough diamond ever discovered in the world. It was in a South African mine in 1905, one that happened to be owned by diamond magnate Sir Thomas Cull-ee-nun
2. The Ba-Hee-ah Emerald
Here is an emerald with a very interesting history, one that has seen it nearly destroyed, stolen, and so much more. The Ba-Hee-ah Emerald was found in Brazil, near Bahia, hence the name. It is one of the world's largest uncut emeralds, which just adds to its value and beauty to some. It is so untouched in terms of refinement that it's actually embedded in rock, but it's estimated to be 341kg.
1. Koh-ee-nor Diamond
The Koh-ee-nor is not only one of the most valuable diamond in the world, it's arguably the most controversial. As it was given to England under controversial circumstances, then placed as the headpiece of the literal Crown to the Queen. Some view it as priceless, others view it at around $200 million, and others view it as high as 1 billion dollars.

In the second installment of the 'Technically Speaking' series, Tom Bruington, mining engineer with Sandstorm Gold, discusses the tools and concepts behind mineral exploration. Tom’s lesson covers both simple and more complicated exploration techniques ranging from mapping to geochemistry to drilling.

In this episode of Mining America I find an Orange red opal. We dig on the side of a cliff and slide down the mountain, and I get an education on opal in the virgin valley.

Finding Gold! Today I find a beautiful Quartz seam with lots of visible gold. I was going to spend the day exploring the claim, but early on in the day I stumble across a quartz outcrop which catches my eye, after a bit of digging I find my first piece with VG (Visible Gold) So I put aside my plans for the day and spend the day digging. I find multiple pieces of the quartz with gold from the seam.
This hydrothermal seam shows free milled gold on quartz. It is also associated with pyrrhotite gold or and arsenopyrite gold ore. This new gold discovery shows most of the visible gold on quartz, gold specimens directly on the quartz.
Part 3 of this series will be us going back with larger tools to get more of the material from this spot.
This video is produced by Dan Hurd, Prospector, Miner, Teacher and YouTuber, as part of his YouTube channel based on educational videos about gold mining, gold panning, prospecting, rock hounding, and mineral collecting.

At The Vision Corporation's mining operations in Afghanistan and Pakistan, the exposed talc is extracted using smaller, hydraulic backhoe shovels. Even at this early stage, the different ore types are sorted as they are extracted.
For more details, please visit: http://thevisioncorporation.biz/blog4/

The area is in a silitified and Pyritized fracture zone 11km long and several kilometers wide in BC Canada.. Which carries multiple gold and VMS deposits. There are hundreds of heavily mineralized outcrops and multiple large deposits. Some mined over a hundred years ago, some are new discoveries.
Host rock consists of gabbro diorite, quartz feldspar these host a schist panel which has multiple outcrops with schists and mineralized quartz veins, there are numerous showings in the area, small amounts of free gold along with multiple sulphides can be found. These outcrops mainly consist of pyrite, chalcopyrite and galena mineralization with some free mill elements. This is an area which has been exposed by a logging company while building a road. Enjoy the show, assay results from two samples are in the video and as always happy gold mining!
Assays were done on several samples sent in yeilding some gold, silver, platinum, palladium and other values the results are at the end of the video!

Did Robert Mugabes security forces seize control of a lucrative diamond field by gunning down hundreds of miners? With shocking evidence now uncovered, Zimbabwe's diamond trade faces suspension.
"We were told here are the guns, sitting in the truck, do you want to stay?" says Andrew Cranswick, CEO of the mining company who owns the rights to mine diamonds in Marange. After his company was evicted, the Marange fields were opened up to the people and tens of thousands of Zimbabweans came to dig, paying the police a commission. Yet the police didn't always play fair - "$15 million worth of diamonds were confiscated", says one former miner  and soon the police were replaced by Mugabes own military. "Mugabe needed a way to buy the loyalty of the army" says Ken Roth, "the military were ordered to kill".
In the first week of November, helicopter gunships launched a massacre on the Marange diamond fields. Evidence has been collected of 200 deaths. Those who weren't killed were raped or crippled. "They told us if we wanted to go home we had to sleep with the men", says one woman, "the soldiers watched and laughed". Next month, the Kimberley process, the international body charged with stopping trade in conflict diamonds, will decide whether Zimbabwe should be suspended. Yet with many Western governments involved in Zimbabwe's diamond trade, a former delegate of the Kimberley process believes this deadly business may yet be protected.

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.

Did you know that gold is extraterrestrial? Instead of arising from our planet’s rocky crust, it was actually cooked up in space and is present on Earth because of cataclysmic stellar explosions called supernovae. CERN Scientist David Lunney outlines the incredible journey of gold from space to Earth.

March 15/16 - In this video I remove some of the loose quartz with a rock hammer and other tools. It started off as 7788.17 grams of gold, quartz, arsenopyrite, chalcopyrite and other.
This video series is to show the preparing of a gold specimen to make it more valuable than the gold content, this will turn out to be a museum quality specimen rather than crushing it and melting the gold.
The chemicals and techniques used in the preparation of this specimen are DANGEROUS and can cause death. This video is for educational purposes and hopefully entertaining as well. PLEASE DO NOT attempt any of these techniques or procedures without proper safety equipment and training

We had a customer send us some very high grade gold quartz ore which we recovered 1.310 troy ounces from only 300 lbs! We ran the quartz through our 1/2-1 ton per hour complete turnkey processor comprised of out jaw crusher, hammer mill, and shaker table modules. The system did a good job of crushing and pulverizing the ore, but the shaker table did a remarkable job of recovering lots of gold that was smaller than 325 mesh.
